Hmmm....off the top of my head, without number-crunching...in no particular order. Just putting out some names, here:
Larry, Reggie, Ray, Kobe...Pistol Pete?
A few others I'm forgetting?
Ray Allen is definitely among the best...I wouldn't say "The" best. Maybe I'm too partial to the Green, but MAN I've seen games in my youth where Larry was just COOKING, lol......
Larry Bird would make the opponents SAD with his shooting...Reggie, too. Pistol Pete was before my time, but I've heard he could cook, too.
Ray is among the best, but to my memory...Larry was just a demoralizing shooter for his opponents...would talk trash while doing it, too lol.
